9. Countershaft Inspection

Countershaft Inspection
1. Inspect the gear and bearing surfaces for wear and damage.





2. Measure the countershaft at points A, B, C, and D. If any part of the countershaft is less than the service limit, replace it.





3. Inspect for runout by supporting both ends of countershaft. Then rotate the countershaft two complete turns while measuring with a dial gauge. If the runout is more than the service limit, replace the countershaft.
